In this paper, using electromagnetic theory, the equations for the total magnetic force on the rails are deduced. Besides this, the equations for the changes of the magnetic force along with time and the running position of the armature under jointed pulse operating current are presented. Then, the equations for changes of the bending stress and shear stress in the rail along with time and the running...
Scientific workflow system (SWFs) is a tool which is used in scientific research. SWFs is a useful tool that brings remote data access and management under distributed infrastructures to the desktop. Because the Scientific workflow is highly data-centric naturally, it makes the scientific data management, analysis, simulation on distributed infrastructures challenging. When scientist use a SWFs to...
Electromagnetic railgun (EMG) use a high-current, high-energy electrical pulse to accelerate projectiles to hypersonic velocities. A pulsed power supply (PPS) that employ capacitors as the energy store are typically used to shape the required electrical pulse. In this paper, the differential equations of projectile moving in the bore has been given and solved. The general pattern of projectile moving...
